Fri, 07 May 2004 11:16 i suppose i should write a tech article but here you go! the big port head is useless on a 7rib bottom end, you will loose horsepower.the small port is a far more effient head as it has a much better velocity into the ports. that said a big port works well on a turbo 4ag as you are craming air in I.E forcing inducting the air in. i use big port for turbo and smallport or twenty valve for atmo. its all to do with port velocity, the small port creates a venturie effect until it cant allow anymore air through, for its given size, which would be about 240{with head work) or so hp. there is alot more to it than above but its a good over view. mick [Report message to a moderator]
